1. Foreword: The B660I white small board has an all-round evolution in appearance and materials.
I don’t know if anyone likes the white ITX mini host like the author, but there are not many new generation white ITX motherboards to choose from on the market.
Recently, Colorful launched a white CVN B660I GAMING FROZEN V20 motherboard, which uses a standard mini-ITX board structure and is only 17x17cm in size.
Compared with the previous generation B560I GAMING FROZEN motherboard, B660I GAMING FROZEN has been comprehensively upgraded in terms of appearance and workmanship:
, full-cover frost condensation cooling system and I/O baffle integrated design
We can It can be seen that the frost cooling system of B660I GAMING FROZEN covers almost the entire area on the left side of the CPU, which not only improves the appearance, but also enhances the heat dissipation effect.
, 8+1 phase 60A power supply circuit
The previous generation product is designed with 6+2 phase power supply, while B660I GAMING FROZEN is 8+1 phase, which enhances the power supply capability of the CPU core. Each phase of
has a 60A DrMOS, an F.C.C ferrite inductor and a 10K alloy solid capacitor. In theory, there is no problem if it is equipped with a non-K version of i9-12900, but we recommend that you still use a non-K i5 or i7 processor.
, 2 M.2 interfaces
The previous generation product only had 1 M.2 interface. This generation is designed with 2 M.2 interfaces, one on the front and one on the back. The M.2 interface on the front of
can support PCIe 4.0 and SATA SSD, and the M.2 interface on the back can support PCIe 3.0 SSD.
, .5Gbps wired network card + Wi-Fi 6 wireless network card
With the popularity of 2.5Gbps routers, B660I GAMING FROZEN has also upgraded the wired network card to 2.5Gbps, and is equipped with an Intel Wi-Fi 6E AX201 wireless module.
has no shortcomings in terms of network.
Colorful CVN B660I GAMING FROZEN V20 motherboard detailed parameters are as follows:

3. BIOS introduction: Supports manual setting of temperature curve
EZ BIOS interface, which can display the temperature, frequency, voltage and other information of the processor and memory.
We can see that there are three modes to choose from in the lower right corner: "Default", "Performance" and "Energy Saving".
fan setting interface can freely adjust the temperature curve. For example, you can set the CPU fan and chassis fan to stop below 40 degrees to achieve zero noise under low load.
CPU overclocking interface, you need to pay attention to the "CPU base frequency acceleration" number, which can be set to a maximum of 200W and can support i7-12700 processor.
When we tested, we used the i5-12600K processor and set the power consumption wall to 130W.
memory support is quite surprising. We are using Netac DDR4 4266MHz memory. XMP2 cannot be enabled on many Z690 motherboards, but this motherboard can boot normally.
In "Advanced Mode", you can modify the settings of the processor, fan, power supply USB, hard disk, etc.
can set the number of CPU cores, turn off energy efficiency cores, etc.
Resizable BAR is also supported. After it is turned on, AMD RX 6000 can get about 8~10% performance improvement.
can directly upgrade the BIOS in the BIOS interface.
4. Performance test: The actual test with i5-12600K is almost the same as the top Z690 motherboard
The test platform is as follows:
. Memory test
Turn on XMP2, the memory frequency is 4266MHz, and the timing is 18-2 2-22-42-64, at this time Gear 2 mode. The measured memory of
reads 58656MB/s, writes 58430MB/s, and copies 55349MB/s, with a delay of 69.3ns.
We set the memory to Gear 1 mode, memory frequency 600MHz, timing 19-26-26-46. The measured memory read of
is 54029MB/s, ingestion is 52290MB/s, copying is 51520MB/s, and the memory delay is 62.1ns.
In 3600MHz Gear 1 mode, the memory read and write bandwidth has been reduced, but the delay has dropped significantly from 69.3ns to 62.1ns.
, CPU performance test
The first is CPU-Z, i5-12600K measured a single-core score of 787 and a multi-core score of 7109. Compared with the top Z690 motherboard, the single-core performance of
is basically the same, but the multi-core performance is about 40 points worse, with a gap of about 0.5%.
followed by CineBench R15, the single-core score of i5-12600K is 277cb, and the multi-core score is 2561cb. The single-core score is only 1 point behind the top Z690 motherboard, and the multi-core score is about 20cb less, with a gap of less than 1%.
, baking machine test
We locked the power consumption of i5-12600K at 130W in the BIOS and conducted the baking machine test. The measured power consumption of the
processor is 124W, the P-core baking machine frequency is 4.4GHz, the temperature is 86 degrees, and the CPU core voltage is 1.18V.
seems to need to adjust the power consumption to 135W to lock the i5-12600K oven frequency at 4.5GHz.
5. Summary: High-quality B660 ITX motherboard worth buying
In recent years, the progress in design and materials used by mainland motherboard manufacturers can be said to be obvious to all. Although there is a slight gap in the BIOS, motherboards like the B660 do not require a very powerful BIOS.
In terms of functions, the BIOS of the Colorful CVN B660I GAMING FROZEN V20 motherboard has all the functions that the BIOS should have. For example, the CPU and system fan can support players to freely set the temperature and speed curve, support direct refresh of the BIOS in the BIOS, support memory overclocking, Supports SAM, supports freely setting the power consumption wall of the processor, etc.
During the test, we also discovered 2 small surprises.
The first is that after we failed to overclock the memory, B660I GAMING FROZEN directly rebooted into the system with the default BIOS settings. This is a small detail. After overclocking fails, there is no need to short-circuit the motherboard battery to manually reset the CMOS.
The second is the Netac Jueying DDR4 4266 MHz memory we used. After turning on XMP, it directly entered the system with a frequency of 4266MHz and a timing of 18-22-22-42-64. We have not been able to successfully start memory with the same settings on a certain Z690 motherboard before.
In terms of performance, we paired it with an i5-12600K processor. According to actual measurements, the gap between its CPU single-core performance, multi-core performance and the top Z690 motherboard is less than 1%.
In terms of materials, dual 2M.2 interfaces, Type-C I/O interfaces, 2.5Gbps wired network card + Wi-Fi 6 wireless network card , etc. are not inferior to the top B660I motherboards from first-tier manufacturers, but it is 999 yuan The price is more than 500 yuan cheaper.
Considering that the B660I GAMING FROZEN motherboard has 3 years of after-sales service, and Colorful also supports personal warranty (most Taiwanese manufacturers do not support personal warranty), there is no reason to refuse regardless of after-sales, performance, workmanship, price or other aspects. Such a beautiful and cost-effective B660 ITX motherboard.
